Saturday puts her weight on the tail gingerly at first. When it doesn't budge, she sits fully on it.

She can't help giggling when the tail wraps around her like an anaconda and lifts. This is definitely going in her top ten weirdest moments.

"Sorry - yeah, I'm stable. Wow, this is new. It really is like a whole extra manipulator limb, isn't it? At least for big stuff - tail would make delicate work hard."
